How to get Azure Storage Account Key

I want to upload a file to an Azure Storage account that is automatically generated (As part of a Service Fabric resource group, with a known name), using C#.

I need to upload the file as a blob to allow it to be publicly available.

The tutorial Get started with Azure Blob storage using .NET uses a connection string stored in the App.config file. Since I want to use the to-be-generated storage account, I can't use such a method.

The prefered method is using the user's AD somehow in order to get the key of the storage account.

This link: Get Storage Account Key shows how to GET it with a Rest request, so I guess there is a way to do it using C# code.

It seems to me, that the solution is using the StorageManagementClient class, which has a StorageAccounts property, though I could not find a way to authenticate it using AzureAd.

I tried using AuthenticationContext.AcquireTokenAsync, and aquiring a token for diffenent resources, for instance: https://management.azure.com/, but when using the token, I get the following error:

Microsoft.WindowsAzure.CloudException: AuthenticationFailed: The JWT token does not contain expected audience uri 'https://management.core.windows.net/'.

When using the resource https://management.core.windows.net/ I get a different error:

Microsoft.WindowsAzure.CloudException: ForbiddenError: The server failed to authenticate the request. Verify that the certificate is valid and is associated with this subscription.

Is there a different resource I should use, different method, or maybe it's impossible?

Please share the code you're using. Also share if you are logging in as yourself to acquire the token. Lastly, for your 2nd error please see this thread: stackoverflow.com/questions/35190866/…. HTH. – Gaurav Mantri

To use the Storage Service Management REST, we need to specify the resource to https://management.core.windows.net/ instead of https://management.azure.com/. And this is using the operate the classic storage account.

The https://management.azure.com/ is the new endpoint for the Azure REST service. If you want to handle the new storage account, you need to use this resource. And below is a sample using the new Azure REST for your reference:

POST: https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resrouceGroupName}/providers/Microsoft.Storage/storageAccounts/{storageAccountName}/listKeys?api-version=2016-01-01
Authorization: Bearer {token}
